I\'m writing an application and my aim is to detect when a user is walking. I\'m using a Kalman filter like this:
In my app, in the onCreate() method of the main activity I am creating a wake lock so that the CPU will keep running if the phone goes on standb/screen turns off.
I\'m developing an app for iPhone (iOS 4.2) which needs to be able to collect large amounts of data from the accelerometer and gyroscope. I\'m current looking at using the CoreMotion framework to get
I did search but I could not find an answer; When interpreting android accelerometer values, how can one translate these values into real world phone translation along X/Y/Z axes?
I have the following code playerPosition.x += acceleration.x * 10; playerPosition.y += acceleration.y * 20;
I want to be able to feature a fairly simple fall detection algorithm in my application. At the 开发者_如何学运维moment in onSensorChanged(), I am getting the absolute value of the current x,x,z value
I am trying to make an application that will act as a sextant (to find the height of an object). Is it possible to use the data from the accelerometer to find the angle the phone is pointing? Ideally,
I am trying to make a circuit which can sense acceleration in the X, Y, Z axis. (e.g. movement straight down should be in, say, Z axis - not X and Y)
How would I implement something that can make use of the iPhone 4\'s gyroscope and accelerometer in order to find out the speed/velocity at which the object is moving?
ive managed to get out the accelerometers values (x,y,z). Is there an easy way to make a circl开发者_如何学Ce move with those values? I would also like it to stop at the edges of the screen. Thanks!I
